Study Notes
Full-Wave Rectifier
- A full-wave rectifier allows both positive and negative half-cycles of the input signal to pass through the load during the entire input cycle.
Output Voltage Frequency
- The frequency of the output voltage in full-wave rectification is twice the input frequency.
Average Value Comparison
- The average value of a full-wave rectified sinusoidal voltage is twice that of a half-wave rectified voltage.
Average Value of Full-Wave Rectified Voltage
- The average value of a full-wave rectified voltage is approximately 0.637 times the peak voltage.
Positive Alternations
- The number of positive alternations in full-wave rectified voltage is twice that in half-wave rectified voltage for the same time interval.
